IMPROVEMENT `|N GRAIN-SEPARATORS.

Specification forming part of Letters Patent Nol 178,257, dated June 6, 1876; application filed June 10, 1875.

To allV whom `it may concern:

Be it iknown fthat we, AARON WIssLER, of Brunersville, and BENJAMIN H. SNAVELY, of Penn'township, both inthe county of Lancaster and State of Pennsylvania, have jointly invented certain Improvements in a Combined ThrashingfMachine, Separator, and Straw- Garrier, of 'which `the following is a specification:`

Our` invention relates to several detached improvements, acting, however, in conjunction in producing certain desirable results in acombined thrasher, separator, and strawcarrier, to perfect the joint action and make the machine as a whole more efticient,lcon sisting of a cap over the spiked cylinder to preventthe annoyance of the dust to him that feeds themachine, toireg'ulate the `stroke or vibrations in the several parts by setscrews, to `widen the steps in the shoe for adjustment to suit the weight of the grain; the manner of constructing the sieve in two or more segments, to prevent clogging; a universaljointed pulley attachment, to ad apt the strapto any position of the endless apron on thestraw-carrier attached; the arrange ment and construction of anl automatic conveyerv and bag-holder combined; all operated by the driving-belt in connection with the thrasher.

The accompanyingdrawings, making a part i of` this specification, with the letters of reference marked thereon, indicate the nature of the construction and combination of the parts,

in which- Figure 1, Sheet 1, is-a perspective view of the entirecombination; Fig. 2, a sectional enlarged view ofthe double adjustable pulleys;

The weighted-arm adjustment for the fan is` substantially the same as in patent to B.H. Snavely, April 5, 1870, No. 101,530, party hereto.

VWe claim noi` special: novelty as relates to the combination of a thrashing-machine, sepyarator, and straw-carrier, `as such are common,

embracing the same general features as alsoi `used by us in our several patents, now jointly combined with certain improvements on the same, which-we deem novel and useful, to` which we shall confine our description 'in ref-:1

erence to thedrawings.l

First, the conical cap G, over thel cylinder,

yfor the purpose of arresting the dust caused. by the revolution of the cylinder, so annoy` ing and injurious to him who feeds the ma. chine, and by which cap itis received and ex-` pelled backward, either onto the machine or among the straw, by connecting the open slot;

Vin the top of the cap with the same. Great ,difficulty has been'experienced, under certain conditions, in ndjustin g the straw-carrier so as` to convey the straw to one side, and yet operate the endless apron with the pulley on the machine at any desired angle. To overcome this difficulty we have devised a rod or jointed brace.

The rod O is bolted to the post u of the machine at one end. The other is hinged to the slotted brace-arm P, which supports the carrier It, and is also held in or on the crossrod d by a hooked hanger, c, Fig. 3J There are, besides, the. ordinary adjustable legs S,` to sustain the straw-carrier R and appliances of the endless apron and pulleys or rollers T. `We employ a double pulley, 7, on ashaft, 6,

Vin a bearing, 5, combining a concave and convex coupling, in combination with a` hanger,

3, and headed binding nut and bolt 4., which Alatter has vertical play in the slot, andthe rounded head admits the play of the ball-and-l with the pulley on the machineand those to.`

operate the endless apron` can be nicely adj usted, under any angle or slope"of ground, to operate with entire satisfaction.

Inasmnch as our fan is selfadjusting,.and

in many cases it is desirable toadjustthe eX-l t y check-block 41, to limit the stroke.

tent of the vibration in the shaking bottom, shoe, and sieves, we place adjusting-screws to each, as shown in Fig. 3--8 betweenthe rockers 17 and 18, above, extending to the shoe, and one below, s', extending to the sieve, another, s, to the tailing sieve or screen W, and

one, 8"', under the shaker-box A, Fig. 4, in a bearing, 43, sets against a cross-piece, 42, and These several screws, however' separated, all act in conjunction to the same end, and consequently co-operative, however adjusted, so that the machine performs its proper functions to produce the desired results.

The shoe and sieve arrangement are shown in place in Fig. 3 and detached in Fig. 7. The ordinary comb 33 and steps 34 and 35 of the shoe are supported on the vibrating hanger 25, on each side. These steps 34 and 35 are, however, made double. The upper slides move in grooves made in the side pieces, in which the step can be widened for cleaning heavy grain, or duly adjusted to the circumstances.

In front of the lower step 35 of the shoe, directly over the second section of sieve 30, there is a triangular dividing-board, 27, with its apex centrally on the top. This protects the j The sieve made with vtwo or three sections and intervening blank spaces is set in a frame, f, connected with extended vibrating side pieces of strap-iron 32, attached behind, and the frame f suspended in front by hangers 24. The third segment is only employed to separate the heaviest grains for seed.

The vibratin g is effected by eccentrics on a shaft, 19, revolved by a bevel-pinion, 45, sup`` ported on the bearing I for the self-adjusting fan-shaft, which is terminated by a bevel-pinion, 46. These ecccntrics operate the rockers 17 and 18, connected, respectively, with the shoe and sieve.

There is an additional outside rocker and rod, 14, extending back to give motion to the tailingscreen W, as seen in Fig. 2, each made separately adjustable by set-screws aforesaid.

The cleaned grain, subjected to the blast of the fan over, under, and through between the sieve, shoe, and shelves, drops into the hopper a." of thevconveyer fr, which is provided with a shaft and wings in the usual form. Ours is also reversible. This shaft has a pulley, V, on a clutch operated by the forked end of a rod, 20, which rod has its other end y connected to the drop-shaft or eccentric of the bag-holder and its valve 13, which shifts the lug out of or into gear with the pulley as it is thrown up ordown on moving or replacing a bag to be filled.

The pulley V may be transferred froml one sideto the other of the shaft, as also the bagholder.

Fig. 6 shows the construction of the bagholder.

The upper cross-plate or top has two holes to set over the pins 22 on the-conveyer. This plate has perforated ears or lugs for a bent rod, 8, weighted by its ball 9, whichl forms a clamp to hold the upper part or mouth of the bag. The'valve 13 forms the clamp, with its -weighted arm 12 for the lower side or mouth of the bag. The shaft or prolonged axis of the valve 13 hasan eccentric bearing for the rod 20 to actuate the clutch on the pulley V. `A board, 39, for supporting the bag is connected by a bolt, 40, to the under. side of the holder. There is also a rod, 38, attached to the under side of said holder, with a hook to connect it with the conveyer.

The mouth of the bag being affixed by the clamp, the lower V- shaped valve clampsthe bag with one wing, while the other forms a chute inside the bag.

When the bag is attached, the ball is thrown forward, and the chuck gears the pulley V with the shaft that operates the conveyer.

When the bag is full, and the valves or clamps reversed, it can be removed while the conveyer is stopped until another bag is secured.

These are the several improvements on the machines built by us under our several pat- @uis-N0. 101,530,Apri 1 5, 1870, to the said' SNAVELY, and Patent No. 108,546, October, 1870, to AARON WIssLER, the other party hereto, as jointly made by us.

We also improved the rake-teethand attachments of cleaners, to work thel straw more effectually, and prevent tan glin g or clogging the teeth. We also apply a top. cross-piece, 37, to prevent grains being driven out by the cylinder. These we simply mention.

We are aware that numerous devices are employed on various machines in use; but we do not know of any substantially like those we have described or specially claimed. Therefore,

What we claim as novel is- 1. In combination with the adjustable-jointed supporting-rod 0 P, the universal-jointed pulley-holder, consisting of the hanging bracket 1 oli its pivot-bolt 2, and provided with a slotted socket-like base, 3, connecting and pivot bolt 4, made adjustable with the pulleyframe 5, all arranged and operating substantially as and for the purpose specified.

2. In combination with a shaking bottom, A, the adjusting-screw S, affixed nut or female screw-block 43, and check-piece 41, operating against the cross-beam 42, in the manner and for the purpose set forth.

3. In combination with the clutch on the. pulley V and conveyer-shaft, the connectingrod 20, valves 13, and Weighted arm 12, the the manner and for the purpose herein men- Whole construe-ted and operated as herein speetioned. ied.
